Waterstones Application process????

I had an interview with Waterstones on Monday, How long will it take for them to contact me if i've got the job or not?

Don't know about Waterstones, but for the few jobs I've had interviews for I've found out between the day after and up to a week after. Try logging onto the online application site, as they will usually update your status there once they make a decision. Good luck!
